摘要：
In order to describe the car following stability of the mixed traffic flow under the condition of Connected Automatic Vehicle mixing，reveal the changing process of mixed traffic flow stability，analyzed the stability of HDV and CACC traffic flow，introduced the mixing rate of CACC，proposed the following model of mixed traffic flow，and derived the stability criteria of mixed traffic flow stability. Analyzed the effects of speed and mixing rate on the stability evolution of mixed traffic flow under single and combination conditions respectively. The results show that：The stability of mixed traffic flow depends on the stability of a single traffic flow and the mixing rate. The critical speed values of the following stability of HDV and CACC single traffic flow are 19.65 km/h and 18.01 km/h，respectively，the speed is positively correlated with the stability of mixed traffic flow. The effect of mixing rate on the stability of mixed traffic flow is related to the speed condition. Under the combined conditions of the two factors，the stability changing trend of mixed traffic flow is diversified. © 2024 Editorial Board of Jilin University. All rights reserved.
